Have had this a few years, help with ID please

Not looking for specifics (which might be difficult because it's not in flower) but at least the group it's in so I can figure out its proper culture.

It's in a 5" pot. (edit maybe a 4")



There's once smooth pseudo bulb but in a recent transplanting it ended up difficult to see (in an effort to get this plant growing towards the center of the pot.)

Also having issues with yellow leaves (has been watered a lot recently, think it's related to that and have stopped) and brown spots:



This recently recovered from scale (the reason for the repotting was to get at all the more difficult areas of the plant.

I've also got one pseudobulb from this with two tiny plantlets doing extremely well sphag-n-bag. Fingers crossed for it!
